RICHARD H. HATE, JR., F CONSHOHOGKEN, PENNSYLVANIA.

BOILER-FLUE CLEANER.

l T0 all whom it may 'concer/n Be it known that I, RICHARD H. Barn, Jr.,

va citizen of the UnitedI States, residing at Conshohocken, in the county of Montgomery and *State of Pennsylvania, have invented new' and useful Improvements in Boiler- Flue Cleaners, of which the following is a specification i My invention'relates to new and useful improvements 1n boiler flue cleaners, and has for its object to provide an exceedingly fines.

tributing pipes from lwhich A still further object of the invention 1s to provide a discharge pipe or header having a number of valves therein which control the supply of steam to a number of dis lead branch pipes, both `the distributing pipes and branch pipes having nozzles which are located at pointsiopposite the ends of the iues.

A still further object of the invention is to provide a single discharge pipe or header connected with a supply pipe, the flow of steam to the discharge pipe being regulated by a valve, an'dtozprovide a series of nozzlesb connected in sets with( the header, the

`supplyfofy lsteam to each set being regulated actuated valve, each of which is lfy a spring aseparate flexible cable, such operated by as a chain.

' A still further object of the invention is to provide a nozzle for my improved flue cleaner, whereby the steam will be given a whirling motion as it enters the fines, so that tbc 'foreign matter may be readily rcmoved.

'Vith these ends in view, this invention consists in the details of construction and combination of elements hereinafterI set forth and then specifically designated by the claims.

In order t at those 'skilled in the art to which this invention appertains may understand how to make and use the same` I will describe its-construction in detail, referring i f Specmcation of-Letters Patent.

Application led November 20., 1913. Serial No. 802,103.

by numeral to the" accompanying drawing forming a partl of this specification. in which- Figure 1, is a front elevation of a boiler showing my improved boiler fine applied thereto, a portion of the front wall and doors being broken away to clearly illustrate the construction. Fig. 2, is a 'vertical longitudinal sectional view thereof. Fig. 3, is an enlarged side elevation of one of the nozzles. F ig. 4, is a longitudinal sectional view thereof. Fig. 5, is an end view thereof: `and Fig. G, is a section at the line (5--6 of Fig. 3. Fig 7 is a side elevation of one of the distributing pipes with its various branches, and the nozzles attached thereto. Fig. S, is a longitlulinal sectional view of a spring actuated valve; and Fig. 9, is a secn tion at the line Sl-tl of Fig. 8, looking in the direction of the arrow. i

In carrying out my invention as here embodied 2 represents a boiler having flues or tubes 3 therein.

'-l denotes my improved boiler flue cleaner which is mounted in front of the boiler within the inclosing walls, so that' the steam therein may be super-heated or dried before passing into the flues, butis of such construction that the draft is not interfered with. Leading from the boiler 2 is a steam supply pipe 5 which is connected with the discharge pipe or header G, and "has a valve 7 situated there in to regulate the supply of the steam to said header. From said supply pipe between the valve 'i' and the boiler leads a drain pipe 8, the ends of which preferably passes through the inclosing walls and enters the ash pit, whereby the water may bc drained from the supply pipe before the steam is turned into the header and said drain pipe has a valve 9 situated therein for opening and closing the same.

The discharge pipe or header C has connected thereto a number of valves l0, each of which is provided with a spring actuated valve stem ll carrying a rotatable valve plug 27 having a plurality of openix'igs-QS tributing pipe 13 having branch pipes 14 connected thereto. The distributing pipes and their branch pipes carry a number of nozzles l5, one of which is opposite each of the tlues 3 of the boiler and each distributing pipe with its branch pipe and nozzles forms a section which is controlled by one -of the valves 10. On the outer end of each at right angles to the first named sheaves Cri and journaled in the bracket 21, secured to the outer face of the front Wall 19, the chains passing through 'suitable openings in said front wall and to the outer ends of said chains' are fastened the handles The nozzles 15 each comprise a threaded .stem whereby they may. be secured to the distributing pipes and branch pipes and a body 24 haring a plurality of spiral openings passing' longitudinally therethrough, which will impart a whirling motion to the, steam as it enters the'tlues, So that the foreign matter may be readily removed.

The operation of the device is as follows: 'l'he valve 9 is lirst open and the water drains from the supply pipe 5 thro-ugh the drain pipe S, after which the .valve 9 isl again closed and the valve 7 in the supply pipe opened, which permits the steam to enter the discharge pipe or header 6 where it is allowed to remain a short time so that the temperature Will completely dry the steam or cause it to be super-heated.v By pulling upon one of the lexible cables 16, thewlieel l2 to which said cable is connected will be rotated against the action'of the spring actuated-valve stem l1, thus open ing thev valve and permitting the steam to into the distributing pipe 13, then into the branch pipeswand through all o? the nozzles oi one section and into the flues opposite to which the nozzles are situated, thus cleaning a number of the boiler flues with-4 out interfering with the ren'iaining flues. iecause oi the whirling motion imparted to the steam as it enters the lues the foreign matter will be virtually scraped from the interior faces of the iiues and carried along with the jetsfot steam and out of the opposite'ends. 1

Of course do not Wish to: be limited t0 the-exact details of constrx ion as herein shown, as these may be va .'cd Within the limits of the appended claims Without de? parting from the spirit of my invention,

Having thus fully described my .invention what I claim as new andusefu'l, 1s
